In this article we will discuss about:- 1. Definition of Biofilters 2. Microbial Potential of Biofilters 3. Biofilter Media 4. Mechanism. Biofiltration is a new technology used to purify contaminated air evolved from volatile organic and inorganic compounds by involving microorganisms. It is a low cost technology gradually becoming popular due to simple operational and waste-removal efficiencies. Biofiltration is the [...]
Following are the factors affecting methane production: 1. Slurry: Proper solubilisation of organic materials (the ratio between solid and water) should be 1:1 when it is house hold type. 2. Seeding: In the beginning, seeding of slurry with small amount of sludge of another digester activates methane evolution. Sludge contains acetogenic and methanogenic bacteria. 3. pH: For the production of [...]
